AP Chemistry is an detailed look at advanced chemistry topics. It goes far beyond the topics of first year chemistry. This makes the course challenging and fun for people interested in chemistry. There is a heavy emphasis on problem solving which means your focus should first be on the relationships between chemical systems. The labs are more involved and require real preparation outside of the classroom.

This level of chemistry is fascinating and fun.

The summer assignment is not a one time event. Bookmark this site so you can visit it every two weeks starting June 15th. If you add the course over the summer make certain you complete each of the sections you missed.

Chemistry is the study of matter and the interactions between matter. The first year class dealt with the first part and AP Chemistry deals with the second part.

Problem solving is about thinking. Here is an exercise to keep your brain active:

If every stable metal and metalloid on the periodic table can form at least one compound with every stable nonmetal how many compounds can be formed?

Last week's answer: There are 84 stable elements (ones that last long enough for us to determine an average atomic mass. 15 are nonmetals and 69 are metals and metalloids which gives us the minimum number of binary compounds is 15 x 69 = 1,035. The actual number is much higher because we can make many different binary compounds for many of the elements (water H2O and hydrogen peroxide H2O2 is an example).


	In the News New Chemical Element In The Periodic Table ScienceDaily (June 12, 2009) — The element 112, discovered at the GSI Helmholtzzentrum für Schwerionenforschung (Centre for Heavy Ion Research) in Darmstadt, has been officially recognized as a new element by the International Union of Pure and Applied Chemistry (IUPAC). IUPAC confirmed the recognition of element 112 in an official letter to the head of the discovering team, Professor Sigurd Hofmann. The letter furthermore asks the discoverers to propose a name for the new element. for the full article go to http://www.sciencedaily.com/releases/2009/06/090611210039.htm Find you own science articles and send me the link.
